Description

REFERENCE TO RELATED APPLICATIONS
The Present Disclosure claims priority to prior-filed Japanese Patent Application No. 2011-092436, entitled “Solar Cell Panel Connector and Solar Cell Panel Coupling Body,” filed on 18 Apr. 2011 with the Japanese Patent Office. The content of the aforementioned patent application is fully incorporated in its entirety herein.
BACKGROUND OF THE PRESENT DISCLOSURE
The Present Disclosure relates, generally, to solar cell panel connectors and panel coupling bodies, and, more particularly, to the coupling of solar cell panels.
Formerly, within conventional solar cell panels, there was installed a junction box for withdrawing to the outside the electric power that had been converted. Multiple solar cell panels were coupled by a cable installed to the junction box. In Japanese Patent Application No. 2006-310866, the content of which is incorporated in its entirety herein, there is disclosed technology for installing a junction box to the edge section of a solar cell panel. However, as disclosed in the '866 Application, the cable is installed directly to the junction box. Accordingly, the operation for coupling the solar cell panels is complex. A purpose of the Present Disclosure is to make the coupling of solar cell panels easy.
SUMMARY OF THE PRESENT DISCLOSURE
To solve the above-described problem, the solar cell panel connector of the Present Disclosure comprises a main unit connector to be installed on the edge section of the solar cell panel, a first relay connector and a second relay connector. The main unit connector possesses a first mating component that has been established on a first side of the direction along the edge section, as well as a second mating component established on the second side of the direction along the edge section. The first relay connector possesses a main unit side mating component that is mountable-removable to the first mating component of the main unit connector, as well as a coupling side mating component established on the opposite side of the direction along the edge section and in opposition to the main unit side mating component. The second relay connector possesses a main unit side mating component that is mountable-removable to the second mating component of the main unit connector, as well as a coupling side mating component established on the opposite side of the direction along the edge section and in opposition to the main unit side mating component. The coupling side mating component of the first relay connector possesses a shape that is mountable-removable to the coupling side mating component of the second relay connector, and the coupling side mating component of the second relay connector possesses a shape that is mountable-removable to the coupling side mating component of the first relay connector. In this way, there is enabled direct installing of the first relay connector established on one solar cell panel to the second relay connector established on another solar cell panel.
Additionally, as a substitute for the first relay connector and second relay connector, there is provided a relay cable on which is disposed at one end a mating component that is mountable-removable to the first mating component of the main unit connector, and on which is disposed at the other end a mating component that is mountable-removable to the second mating component of the main unit connector. In this way, there is enabled interposing of the relay cable between the main unit connector established on one solar cell panel and the main unit connector established on another solar cell panel.
Additionally, the first relay connector that has been mounted to the main unit connector protrudes outward from the end section of the first side of the solar cell panel, and the second relay connector mounted to the main unit connector protrudes outward from the end section of the second side of the solar cell panel. In this way, one-dimensional coupling of multiple solar cell panels is performed easily.
Additionally, the main unit side mating component of the first relay connector and the main unit side mating component of the second relay connector provide a girder component on which is disposed a hook component for latching, and on the first mating component and on the second mating component of the main unit connector there is formed a channel to which the described girder component is inserted and formed a hook component for engaging with the formerly described hook component. In this way, there is enabled suppressing of relay connector release from the main unit connector. It is also acceptable for the described girder component to be capable of elastic deformation in the inner surface direction of the solar cell panel. In this way, there are thinner mating components of the main unit connector and the relay connector in the thickness direction of the solar cell panel.
Additionally, one of either the coupling side mating component of the first relay connector or the coupling side mating component of the second relay connector provides a girder component on which is disposed a hook component for latching, and on the other of the components there is formed an insertion hole into which the girder component is inserted and formed a latching hole into which the hook component latches. In this way, there is enabled suppressing of relay connector release from the main unit connector. It is also acceptable for the described girder component to be capable of elastic deformation in the thickness direction of the solar cell panel. In this way, because the mating components of relay connector companions are positioned between two solar cell panels, the girder component has difficulty interfering with the solar cell panel, even when the girder component is elastically deformed in the thickness direction of the solar cell panel.
Additionally, the main unit side mating component and the coupling side mating component for one of either the first relay connector or the second relay connector respectively provide a girder component on which is disposed a hook component for latching, and the direction for which elastic transformation is possible for the girder component established on the main unit side mating component is made orthogonal to the direction for which elastic transformation is possible for the girder component established on the coupling side mating component. In this way, by causing reciprocal overlap of parts of the girder components, there is ability to shorten the distance between the main unit side mating component and the coupling side mating component.
To solve the above described problems, the solar cell panel connector of the Present Disclosure provides a main unit connector to be installed to the edge section of a solar cell panel, as well as a first relay connector and a second relay connector. The main unit connector possesses a first mating component disposed on a first side of the direction along the edge section and on which is placed a terminal that is electrically connected to the electrode of a first polarity of the solar cell panel, and possesses a second mating component disposed on the second side of the direction along the edge section and on which is placed a terminal that is electrically connected to the electrode of the second polarity of the solar cell panel. The first relay connector possesses a main unit side mating component that is mountable-removable to the first mating component of the main unit connector and on which is placed a terminal that will be electrically connected to the second polarity electrode of another solar cell panel. The second relay connector possesses a main unit side mating component that is mountable-removable to the second mating component of the main unit connector and on which is placed a terminal that will be electrically connected to the first polarity electrode of another solar cell panel. In this way, because there is provided a first and second relay connector that are mountable-removable to a main unit connector that is installed at the edge component of a solar cell panel, coupling of solar cell panels can be performed easily.
To solve the above described problem, the solar cell panel coupling body of the Present Disclosure also provides a plurality of solar cell panels as well as a plurality of solar cell panel connectors, disposed on each of the solar cell panels, which connectors are to be reciprocally coupled. Each described solar cell panel connector provides a main unit connector to be installed on the edge section of a solar cell panel, a first relay connector, and a second relay connector. The described main unit connector possesses a first mating component that has been established on a first side of the direction along the edge section, as well as a second mating component established on the second side of the direction along the edge section. The first relay connector possesses a main unit side mating component that is mountable-removable to the first mating component of the main unit connector, as well as a coupling side mating component established on the opposite side of the direction along the edge section and in opposition to the main unit side mating component. The second relay connector possesses a main unit side mating component that is mountable-removable to the second mating component of the main unit connector, as well as a coupling side mating component established on the opposite side of the direction along the edge section and in opposition to the main unit side mating component.
